Tire Diameter
20" tires on a 2013 Ram 1500 have a 32.5 diameter 17" have a 31.7 diameter. What would be the apparent ratio or formula to arrive at such based on 3.55 gears.

By using the above chart, I found that it was not a good idea to put larger (wider) tires on the truck. They look cool but it effectively lowers your gear ratio, not useful for towing.
